SAFETY ATTACHMENT FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 235,454, dated December 14, 1880.

Application filed October 28, 1880.

To all whom it may concern Be it known that I, JAMES ROBERTS, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Safety Attachments for Watches, of which the following is a specification.

Figure l is a side view of the improvement shown as applied to a watch. Fig. 2 is aplan view of the improvement. Fig. 3 represents the position of the improvement when the watch-case is being opened.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish safety attachments for watches, to prevent them from being removed from the pocket without the knowledge of the owner.

The invention consists of a plate or ring having scalloped edges, which is slipped over the stem of the watch. The said plate projects horizontally from the stem in such manner that when the watch is carried in the pocket the plate will so nearly fill the pocket that when a thief attempts to remove the watch the edges of the plate will catch in the lining of the pocket and alarm the owner; and if the thief grasps the scalloped plate, then the pressure of his fingers in the narrow space between the plate and pocket will be felt by the owner of the watch.

A is a disk or plate of rubber, which may be circular or slightly oval, and has its edge scalloped. Through the center of the disk or plate A is formed a circular aperture, B. In the body of the disk A, upon the opposite sides of the aperture B, are formed slots 0, as shown in Fig. 2.

The aperture B should be of such a size as to receive the stem of a watch, the slot 0 allow- (No model.)

in g the plate A to be readily passed over the guard-ring of the watch-stem.

The middle part of the plate A is thickened, as shown at D in Figs. 1 and 3, to give greater firmness to the said plate.

With this construction, when the plate A is placed upon the stem of the watch and the watch is placed in the pocket, the watch cannot be withdrawn from the pocket by a pickpocket or other person without the knowledge of the owner, as the scalloped edge of the plate A hangs upon the sides of the pocket and catches against the binding of the pocket, so that the owner will necessarily feel the movement and bc able to prevent the theft. Also, if the pickpocket should insert his thumb and fingers into the pocket to take hold of the attachment and thus remove the watch, he must press upon the pocket so much as to cause the movement to be felt. ln the case of a spring-cased watch, when the guard-ring is grasped by the thumb and fingers to press against the spring to cause the case to open, the pressure of the fingers against the lower part of the plate A will cause the upper part of the said plate to incline outward, so as to be out of the way of the moving part of the case, as shown in Fig. 3.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A safety attachment for watches, consisting of a plate or disk of rubber having a scalloped edge and adapted to be placed upon the stem of a Watch, substantially as and for the purpose set forth.

JAMES ROBERTS.
